BACKGROUND: This paper examines the ability of people who are blind to construct a mental map and perform orientation tasks in real space by using Nintendo Wii technologies to explore virtual environments. The participant explores new spaces through haptic and auditory feedback triggered by pointing or walking in the virtual environments and later constructs a mental map, which can be used to navigate in real space. METHODS: The study included 10 participants who were congenitally or adventitiously blind, divided into experimental and control groups...

Within the NHS and other health service providers, alphanumeric clinical coding has been introduced as a common language to interpret and compare mortality and morbidity data (1) . The two systems of clinical coding commonly utilised are the International Classification of Diseases 10 (ICD-10) devised by the World Health Organisation(1) and the Office of Population Censuses and Surveys 4 (OPCS-4) published in the UK by the Health and Social Care Information Centre (2) .

Gene network (GN) inference from temporal gene expression data is a crucial and challenging problem in systems biology. Expression data sets usually consist of dozens of temporal samples, while networks consist of thousands of genes, thus rendering many inference methods unfeasible in practice. To improve the scalability of GN inference methods, we propose a novel framework called GeNICE, based on probabilistic GNs; the main novelty is the introduction of a clustering procedure to group genes with related expression profiles and to provide an approximate solution with reduced computational complexity...

The most frequent postoperative complications after an ankle fracture are usually skin related. We present the results of a retrospective study of 112 patients with ankle fracture who had undergone open reduction and internal fixation from January 2014 to December 2014. The following features were analyzed: patient comorbidities, fracture type, the presence of an open fracture or fracture-dislocation, timing and duration of surgery, preoperative glucose level, and short-term complications (i.e., blisters, wound dehiscence, deep and superficial infections, and reintervention)...

Authors, readers, and editors share a common focus. Authors want to publish their work. Readers want to see high-quality, new information. Referees and editors serve to ensure that authors provide valid conclusions based on the quality of information that readers want. Common to each of these roles are instructions to authors. However, these are typically written in an uninspiring, legalistic style, as if they are a set of rules that authors must obey if they expect to get published. This renders the instructions boring and oppressive, if not forbidding...

BACKGROUND: The rate of hospital-based acute care (defined as hospital transfer at discharge, emergency department [ED] visit, or subsequent inpatient hospital [IP] admission) after outpatient procedure is gaining momentum as a quality metric for ambulatory surgery. However, the incidence and reasons for hospital-based acute care after arthroscopic shoulder surgery are poorly understood. METHODS: We studied adult patients who underwent outpatient arthroscopic shoulder procedures in New York State between 2011 and 2013 using the Healthcare Cost and Utilization Project database...

Terminal hip flexion contributes to increased strain in peripheral nerves at the level of the hip joint. The effects of hip abduction and femoral version on sciatic nerve biomechanics are not well understood. A decrease in sciatic nerve strain will be observed during terminal hip flexion and hip abduction, independent of femoral version. Six un-embalmed human cadavers were utilized. Three Differential Variable Reluctance Transducers (DVRTs) sensors were placed on the sciatic nerve while the leg was flexed to 70° with a combination of - 10°, 0°, 20° and 40° adduction/abduction...

Importance: Management of appendicitis as an urgent rather than emergency procedure has become an increasingly common practice in children. Controversy remains as to whether this practice is associated with increased risk of complicated appendicitis and adverse events. Objective: To examine the association between time to appendectomy (TTA) and risk of complicated appendicitis and postoperative complications. Design, Setting, and Participants: In this retrospective cohort study using the Pediatric National Surgical Quality Improvement Program appendectomy pilot database, 2429 children younger than 18 years who underwent appendectomy within 24 hours of presentation at 23 children's hospitals from January 1, 2013, through December 31, 2014, were studied...

Hemorrhage is the most preventable cause of posttraumatic death. Many cases are potentially anatomically salvageable, yet remain lethal without logistics or trained personnel to deliver diagnosis or resuscitative surgery in austere environments. Revolutions in technology for remote mentoring of ultrasound and surgery may enhance capabilities to utilize the skill sets of non-physicians. Thus, our research collaborative explored remote mentoring to empower non-physicians to address junctional and torso hemorrhage control in austere environments...

Calorespirometry is the simultaneous analysis of the rate of heat emission (Rq), O2 consumption (RO2) and CO2 production (RCO2) by living systems such as tissues or organism cultures. The analysis provides useful knowledge about thermodynamic parameters relevant for e.g. biotechnology where parameter based yield maximization (fermentation) is relevant. The determination of metabolism related heat emission is easy and normally done by a calorimeter. However, measuring the amount of consumed O2 and produced CO2 can be more challenging, as additional preparation or instrumentation might be needed...

The determination of the relative isotopic abundance by secondary ion mass spectrometry of (236)U in uranium-containing material is complicated by the presence of (235)U(1)H(+) ions at the same nominal mass as the uranium isotopic peak. The net intensity of the (236)U signal is usually determined by a peak-stripping procedure, whereby the (235)U(1)H(+) contribution is obtained by applying the (238)U(1)H(+)/(238)U(+) ratio to the (235)U(+) signal. The subtraction of one signal from another has consequences for the uncertainty of the final (236)U abundance determination that may be especially significant when the amount of sample is limited, as is the case with small uranium particles that are of great interest for nuclear safeguards...

Lactococcus lactis is one of the most commonly used lactic acid bacteria in the dairy industry. Activation of competence for natural DNA transformation in this species would greatly improve the selection of novel strains with desired genetic traits. Here, we investigated the activation of natural transformation in L. lactis ssp. cremoris KW2, a strain of plant origin whose genome encodes the master competence regulator ComX and the complete set of proteins usually required for natural transformation. In the absence of knowledge about competence regulation in this species, we constitutively overproduced ComX in a reporter strain of late competence phase activation and showed, by transcriptomic analyses, a ComX-dependent induction of all key competence genes...

BACKGROUND: There are no recommendations on the optimal dosing for cryoablation of atrial fibrillation (Cryo-AF). OBJECTIVE: We developed and prospectively tested a Cryo-AF dosing protocol guided exclusively by time-to-pulmonary vein (PV) isolation (TT-PVI) in patients undergoing a first-time Cryo-AF. METHODS: In this multicenter study, we examined the acute/long-term safety/efficacy of Cryo-AF using the proposed dosing algorithm (Cryo-AFDosing, n=355) against a conventional, non-standardized approach (Cryo-AFConventional, n=400) in a non-randomized fashion...
